org.ng.

Awọn alaye Idahun

In the URL https://waec.org.ng, the domain name is "waec.org.ng". A domain name is a unique name that identifies a website on the internet. It is part of a larger internet address called a URL (Uniform Resource Locator), which specifies the exact location of a web page or resource on the internet. In the given URL, "waec.org.ng" is the domain name. The ".org.ng" is the top-level domain (TLD) for Nigeria, and it indicates that the website is operated by an organization based in Nigeria. The "https://" portion of the URL specifies the protocol being used to access the website, which in this case is HTTP Secure, or HTTPS. The "www" portion is a subdomain that is used to indicate the specific server that hosts the website. However, many websites nowadays omit the "www" subdomain and simply use the domain name. Therefore, the correct answer to the question is "waec.org.ng" is the domain name in the given URL.
